Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

First AI-enabled POCUS app for detecting pleural effusion and atelectasis earns FDA clearance
The apps are embedded into the Exo Iris transducer, which can be plugged directly into a smartphone, utilized anywhere and without the internet.
Symptom-detected breast cancers more likely to require mastectomy, chemotherapy
New research adds to the “strong evidence” supporting screening guidelines and highlights the importance of women adhering to clinical recommendations.
Shoulder ultrasound effectively detects insulin resistance, even before abnormal labs
POCUS could represent a quick, easy and affordable way to detect signs of insulin resistance before it progresses into diabetes, researchers suggest.
Contrast-enhanced mammography significantly improves early cancer detection
New trial results suggest CEM could enhance breast cancer detection beyond DBT exams when patients are faced with barriers to obtaining an MRI.
Bayer seeks FDA approval for gadoquatrane, its latest low-dose GBCA
The investigational agent uses 60% less gadolinium without sacrificing image quality, according to recent clinical trial findings.

Age and workload affect reader performance for screening mammograms

Age, specialty training and reading volume give readers an edge over their peers when it comes to screening mammogram interpretations.

6 pointers on POCUS leadership in the ED (and potentially beyond)

Has point-of-care ultrasound outpaced hospitals’ capacity to incorporate the technology without anointing any particular specialty its proper guardian? The case could be made.

3D camera guidance meaningfully aids patient positioning, dose reduction

Regardless of a patient’s body mass index, using a scanner-integrated 3D camera for situating CT patients on the table can optimize not only patient positioning but also radiation dose.

CTA-based radiomics can reliably estimate time since stroke onset

Radiomics features could be especially useful for determining TSS in scenarios where clinical data is lacking or unreliable, such as when patients have altered mental status.

New wearable device, no bigger than a stamp, uses AI to deliver on-the-go cardiac imaging

New stamp-sized wearable device uses AI to deliver on-the-go cardiac imaging

The device, designed to be worn for up to 24 hours at a time, uses ultrasound technology and artificial intelligence to track how much blood the user's heart is pumping.

Photon counting cuts CTA contrast dosage 25%

Not only does the low-volume contrast protocol preserve supplies, it also protects patients who might be vulnerable to adverse reactions and/or side effects from contrast use.

Cardiologists use video-based AI model to ID coronary artery disease

A team of specialists out of Cedars-Sinai developed the deep learning model using TTEs from nearly 3,000 patients.
